A fuse is a low-resistance electrical element used in electrical circuits. Fuses are designed to protect the cable from becoming overloaded and causing electrical fires. The BK/S504-2.5A is a type of fuse that can be used in a variety of applications. This article will discuss the application field and working principle of the BK/S504-2.5A.

The BK/S504-2.5A is a current-limiting fuse designed for use in low-voltage systems. It is suitable for use in residential, commercial, and industrial systems. It is designed to protect primarily against overcurrent caused by short circuits, and secondarily against overloads. The fuse is UL listed and CSA certified for use in branch circuits. It can also be used for current-limiting purposes in branches of power distribution systems.

The BK/S504-2.5A has a nominal current rating of 2.5A, with a maximum interrupting rating of 10kA at 125/250V. It has a breaking capacity of 500A at 125/250V. It has a time-delay rating of 10 seconds at 500A and a voltage drop of 2.5V or less. The terminal array is of the type NEMA 2-4-4-2, making it suitable for use in dual-pole applications.

The working principle of a fuse is relatively simple. The fuse contains a carefully measured metal strip or wire known as the “fuse element”. This element is connected in series with the electrical circuit. When an overcurrent flows through the circuit, the fuse element heats up, exceeding its melting temperature and breaking the circuit.

The BK/S504-2.5A features a low voltage drop rating, making it ideal for use in sensitive electrical systems. The current-limiting capabilities of the fuse protect against overloads and short circuits. The low voltage drop rating also ensures that the voltage drop across the fuse does not significantly impact the voltage applied to the circuit. Finally, the NEMA 2-4-4-2 terminal array allows for dual-pole applications, making it ideal for use in branch circuits.

In conclusion, the BK/S504-2.5A is a low-resistance electrical element designed for use in residential, commercial, and industrial systems. It is current-limiting, meaning it will protect against overcurrent caused by short circuits and overloads. It has a low voltage drop rating, a nominal current rating of 2.5A, and a NEMA 2-4-4-2 terminal array. The BK/S504-2.5A is an ideal fuse for use in low-voltage applications, offering protection and reliability in one package.
